And that was my problem, I didn't realize I could add USB connected devices, as PCI devices to my VM. I passed through the USB deivces, then added the ports as PCI devices and now thatnks to you guys, my DCR-2650 records and plays LiveTV without stutter. TV streaming may have worked fine with the HD5450, but for $120, I quite like the 7750 and will stick with it. Thanks again to everyone that provided input in this thread..
Hate to press my luck, but was wondering if anyone could help me map my USB ports, so I only passthrough the ones I need to. I have my DCR2650 and a Cisco tuning adapter connected to the 2 rear USB ports. lsusb reports the following, I was hoping someone could help me figure out which devices I need to passthrough, so that I only assign the 2 USB ports I am actually using.
